Development of Lightning Discharge Observation - From the Troposphere to the Upper Atmosphere and on Planets -
Lightning is a very common luminous phenomenon to us, but still has many unsolved mysteries. This article outlines the latest observations of and research into lightning, and introduces an observation plan of the solar system's planetary atmosphere with a space telescope now under planning. An article by Yukihiro TAKAHASHI at the website of Japan's Institute of Space and Astronautical Science.
Planet Earth may have 'tilted' to keep its balance, say scientists - Princeton University news release
Imagine a shift in the Earth so profound that it could force our entire planet to spin on its side after a few million years, tilting it so far that Alaska would sit at the equator. Princeton scientists have now provided the first compelling evidence that this kind of major shift may have happened in our world's distant past.
Space Gas Vortices Carrying Source Particles of Aurora
The Aurora shinning in the night sky is generated by high-speed charged particles entering the earth's atmosphere. These charged particles originate from the solar wind. This article outlines the latest research and new discoveries regarding solar wind and the earth's magnetosphere, and introduces a future plan for formation-flight observation by multiple satellites. An article by Hiroshi HASEGAWA at the website of Japan's Institute of Space and Astronautical Science.

Early Earth and Mars - Astronomy Magazine article
A team of scientists has found that terrestrial planets such as the Earth and Mars may have remained molten in their early histories for tens of millions of years. The findings indicate that the two planets cooled slower than scientists thought and a mechanism to keep the planet interiors warm is required.
